MetroRock's indoor facilities foster vertical exploration with help from experienced instructors and various climbing terrains. During the Basic Top Rope Climber class, students bedecked in rental equipment and anti-gravity shorts master scaling essentials, such as knot tying, safety commands, and harnessing skills to help ace MetroRock's belay check. More-experienced guests use the 10-pass punch card to don shoes, harnesses, belay ATCs, and chalk before paving paths toward the ceiling on one of the area's handgrip-speckled climbing walls. Swarms of up to 20 people can spend two hours exploring the High Ropes Challenge course, perched 25 feet above the ground with a web of rope obstacles and a zipline, which fosters balance and trains actors for roles in Planet of the Apes.
